Commissioning
EP7402-0057 34 Version: 1.3
Possible results of the test run
• If the motor rotates continuously: skip to next step [
}
35] of commissioning.
• If the motor does not rotate continuously:
◦ Set the output variable "Enable" to 0
◦ Check the status bits in the input variable "Device Diag".
◦ Evaluate the status bits with the help of the table below.
◦ Set the output variable "Reset" to 1. (this resets the status bits)
◦ Set the output variable "Reset" to 0.
◦ Repeat the test run: to do this, set the output variable "Enable" to 1.
Set bit in "Device Diag" Possible reasons Solution
(none) The output variable "Velocity" is
smaller than the parameter
8020:09 "start velocity". Check the calculations.
"Channel 1 motor overload I2T
error" The output current is too high.
Reduce the value of parameter 8023:14
"Sensorless offset scaling" [
}
49] .
"Channel 1 commutation error" The conveyor roller is loaded
1)
Remove any load from the conveyor
roller.
The output current is too low.
Increase the value of parameter 8023:14
"Sensorless offset scaling" [
}
32] .
"Rampup velocity" is too high
1)
Check the calculation of the parameter
8023:19 "Rampup velocity" [ } 32] .
If the calculations are correct, reduce the
value of this parameter.
"Rampup needed switchover
events" is too low. Increase the value of parameter
8023:21 "Rampup needed switchover
events" [
}
32] .
Incorrect motor parameters
Check the motor parameters [
}
30]
The motor is too weak
1)
Insert a gear unit and recalculate all
parameters.
1)
Especially likely when the motor makes a sound with ascending pitch.
